To all 'whom t may concern:

Be it known that l, ARTHUR J. DAANE, a-y

citizen of the United States, residing at Chicago, in the county of Cook and State of illinois'q have invented a certain new and useful Improvement in Ink-Distributing Rollers, of which the following is Va full, clear, concise, and exact description, reference being had to the accompanying drawings, formingV a part of this specification.

Y The invention relates to ink distributing means for printing presses, and particularly for distributing the ink upon the inking rolls of a platenv press.

lt is an object of the invention to provide means for evenly and uniformly applying inl; to the printing surface, and particularly the inking rolls which contact with and distribute the ink upon said printing surface, thus insuring a relatively higher grade of work owing to the more uniform application of the ink to the printing' surface rlhe invention also contemplates the provision of means whereby certain parts may be adjusted to compensate for wear between them, and also a means whereby the parts may be efiiciently lubricated and readily taken apart forrepairs.

lt is a further object of the invention to provide a structure whereby the distributing device may move relatively to itssupport so as to compensate for inequalities of the inlring rollers with which it is associated and also to compensate for Vvariations in contour or shape of the trac'lrupon which the distributor operates when in action.

rllhe invention also contemplates various details of construction which cooperate with each other and lend themselves to produce a simple and effective construction.

The invention will be explained' in detail and more thoroughly understood wheny read in conjunction with the accompanying drawings, in which- Fig. l is a side elevation of a portion of a printing press showing the application of the invention thereto;

Fig. 2 is a plan view showing theinking and distributing rolls in cooperate relation to each other; l

Fig. 3 is a sectional view of theink dis'- tributing rolls showing the mechanism einployed for accomplishing the invention; and

Fig. 4l is a detail side elevation of a bracket employed in conjunction' with the ink distributing roll shown in Fig. 3.

h The invention will beveizplained in conjunction withV the well known platenpress,

in which the ink rollers travel from Vthe i which form the basis` of this application are respectively arranged between the' inl;-V ing rolls andl secured to the inlring roll carriages 12. The distributor roll includes a mechanism whereby it is caused to reciprocate with respect to the inlringirolls and also to'rotate with the same during its movement across the type and plate-11.

This distributor roll and associated mechanism are mounted upon the hollow shaft 13, the opposite ends of which are 'flattened and movably held inthe brackets or sup-v ports 14A-14E movably secured to the inking roll carriage. These brackets will be eX- plained in detail hereinafter. The opposite ends of this shaft are each provided with a pin 15 which cooperates with the inlring roll carriages and hold the shaft against later-al movement with respect thereto. This shaft has ay tubular metallic roller 16 arranged thereon, it being supported at its opposite ends by Yclosures 17e-17a. The closure 17 is Vprovideiil with the external threads 18 whichpermitI this closure to be threaded intothe end of the tubular roller lyand held with 'relation to the roller. This closure is` also provided with the internally threaded Vportion19,rand is also provided withl the llugs 20 and 21. The threaded portion of this closure cooperates withy ay threaded sleeve 22, which is arranged upon the shaft and causes the tubular meniber to reciprocate with relation to the shaft assaid member rotates. The tubular shaft 13 has one end thereof threaded and providedy with the adjusting and lock nuts 23 and 24, respectively. One of these nuts bears against one end of the threadedsleeve 22,A and as the vnut isadjusted along the shaft-'this sleeve is adjusted also. The 'opposite Vend of this sleeve is provided with the'circumfere'ntial flange 23a and is further providedv with the diametrically disposed recessV 24a for the reception of the projections 25 provided upon the elementl 26 which forms one part of a friction clutch. This clutch also includesthe friction material 27 the shaft the tension of vided with the projections and the element 28. This element 28 is provided with the tubular projection 29 which is slotted at 3() for the reception of the pin 31 which is driven through said shaft. A Vcoiled expansion spring 32 abuts against the end of the element v28 and reacts between this. element andthe pin 33.

From Vthe foregoing description it is evi` dent that by adjusting `the nuts 23, 24 Vupon this spring may be varied, so as to insure the proper frictional contact betweenthe elements 26, 27 and 28,

and also compensate for any wear betweeny these parts. By utilizing a clutch'composed y' of separable elements which'have a connection with the threaded sleevey 22 such as above outlined, the faces of the clutch elements are always maintained in substantial parallel relation to each other regardless of i? any deflection of the shaft upon which they are mounted.l

The threaded sleeve said closure reaches this point in its travel "along the shaft. This lug and projection cooperate and rotate the sleeve 22 when this end of the roller reaches its limit of travel inthis direction, thus preventing breakage of the parts. l y

The projection 34 is arranged adjacent the outermost end of the threaded'sleeve and cooperates with the .projection V of the closure and is provided for the i purpose i* above referredto when Vthe reciprocab'le roller Vreaches its limit of movement in this direction. The` clutch hereinbefore referred to permits of this relativerotation ofthe y the mechanism within the tubular sleeve, yet under normalconditions prevents any relative rotation thereof, so that as the roller V16 is rotated through the medium of its contact with the inking rollers, itr will'be reciprocated along the shaft and with respect'to the inking rollers, thereby spreading theink evenly upon the inking rollers andy resulting in accomplishing This Vshaft is provided with means whereby roller maybe readily lubricated without nece-ssitating the' disassociation of the parts. To accomplish this the tubular Vshaft is.. provided With Van aperture 40 throughwhich lubricant may be introduced which finds its Vway to the parts arranged upon said shaft. Therbrackets or supports 14l are mounted uponV the inking roll carriages 12 and are constructed to provide a means whereby the ink distributing rollei may move relatively to the carriages and the inking rolls to comensate forvarious conditions such as herein l before outlined. Thesebrackets being idenbetterY work.

tical in construction with each other the construction of one will suffice for an understanding of both. y

These brackets 14 include the vertical porl tion 42v which forms a housing and the laterally projecting portions 43 and 44. These Y portions 43 and 44 are each provided with a slot 45 to accept the bushing 4d which isv y provided with a collar 47. l.This bushing is of a length which is somewhat greater than the thickness of Vthe portions 43 and 44,

and thus provides a slight clearance between'the collar and said lateral projections, so that these brackets may. move with relation to theinking roll carriage to which they areattached. A bolt 48 is passed through the bushing and threaded into the inkiiig`roll carriage, and by virtue of the vfact that the bushing is of a greater length` than the width of these projectionsj the bushing and the bracket may be movably lbut securely fastened to said carriage. The

portion 42 is provided with a vertical slot 49 to accept one of the flattened ends of the tubular shaft 13. This portion is provided with a threaded aperture 50 for the reception of the threaded adjustable member 51 having the knurled finger pieceV 52.` This member 51 `is provided with a plunger 53 which has the reduced portion `54 upon which is arranged the coiled spring rwhich reacts between the shouldered portion of the plunger and the end of the adjustable element.` The uppermost end or the reduced portion of the plungeris upset so as to p re-` vent theseparation ofthe plunger andthe member 51. A winged set nut 56 is 'arranged upon the member 51, and is provided to lock the member 51 in adjustedv position with relationto the bracket.

From the foregoing description it is evident that the bracket may move laterallyv with respect to the inking roll carriage and that the distributing roller may in addition move Ain Aa vertical direction Ato said carriage, VVand thus compensate for shrinkage and for other inequalities and conditions of the inkiiig rollers, and the track over which the structureoperates." Y Y From the foregoing description itis evident thatV an arrangement of elements is employed whereby the various objects may be vsimply and efhciently accomplished. However various other larrangements may be resorted Vto withoutV Vdeparting from the spirit of the invention as expressed inthe appended claims forming a parthereof.

What I claim and desire to cover by Let-A ters Patent is:
